Sterling 10.5 axle

This corrected a known, but rare, issue of the pinion yoke nut working loose.

For model year 2000 - 2004 trucks, the F-150 7700 offered this axle and the F-250 light duty was discontinued.

All 4x4 came with limited slip (L on tag), it can also be determined from the axle code on the door jamb vin label.

In 1999 Ford revamped their heavy trucks, including their own Sterling axle.

The new axle also came with disc brakes and a unique 8x170 mm (6.7 in) metric lug pattern.
